Relation of Right Ventricular Dilation After Pulmonary Valve Replacement to Outcomes in Patients With Repaired Tetralogy of Fallot

The rationale for timing of pulmonary valve replacement (PVR) in patients with repaired Tetralogy of Fallot (rTOF) has focused on pre-PVR threshold values of indexed right ventricular end-diastolic volume (RVEDVi) that lead to normalization of right ventricular (RV) size after valve implantation. The goal of this study was to determine whether persistent RV dilation after PVR is associated with adverse clinical outcomes. Subjects with rTOF who...
